  title: Hookdeck Retry a Failed Event
  summary: Find the most recent failed event, inspect it, and retry delivery.
  description: >-
    A core operations flow for recovering from a failed webhook delivery. The
    workflow lists events filtered to the FAILED status, branches on whether any
    were found, reads the top failed event to capture its delivery context, then
    retries it so a new delivery attempt is made to the destination. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.

    failed event and retries it, capturing the new attempt id.
